Abstract (en)

[origin: US4560951A] A voltage-controlled oscillator includes an amplifier having two emitter-coupled differential amplifier stages, and in whose feedback network, connected in series, are a 3dB-90 DEG coupler and a surface-wave transmission line. Two variable capacitance diodes are connected to the two terminals of the coupler that are not used as input or output terminals, and a frequency control voltage is applied to both diodes. The oscillator is particularly well-suited for the transmission of digital signals with transmission speeds of over 100 Mbit/s.
